Oh, so this has been a condition he's had prior to you having him, and it was drained before you got him at least once? I see, I'm sorry, I didn't at all understand what you were saying...Yes, that first vet is clueless...I hoped you stopped giving him the Antibiotic then, just like I said, he was taking harsh meds that could stop him from eating and make him lethargic for no reason...This is extremely common and actually has literally killed a lot of otherwise healthy beardies who had a very small, simple to solve issue. Drives me mad...
So he's doing better, that's good...Is that area on his face looking better then? Did he drain it again? Did he happen to mention why he has this cyst, or why it comes back after its drained (that's not typically how a "cyst" works)? Honestly, and I'm not saying this to be smart or condescending towards this new vet who treated him prior, but if he was my beardie I would absolutely get a simple skin scraping test done to the area to actually identify what it is and what's causing it, because #1) it shouldn't keep coming back and need to be drained if it's just a simple cyst, and #2) why put the poor guy through this every so many months if you can actually diagnose the cause and what it actually is and possibly cure it forever? Why make him go through getting the entire side of his face swell up with fluid (which not only looked extremely painful but surely hurt him when even eating) and then have to go through an extremely stressful vet trip and needle aspiration every few months or whatever the time period is between it happening? A skin scraping test costs very little, doesn't cause pain (much less than draining it repetitively for the rest of his life will), and may not only end his trouble but will save you vet trips and money...And it will also end the risk that exists of him getting a horrible infection when this happens, and the risk of the cells eventually turning into something very serious in the future, which it very well could. Or it could grow to be deeper and over a larger area each time it happens...So I'd get it sorted out ASAP to save you both a lot of headache...
